T0 at whom it may concern.-

Be it known that we, ERNEST THOMAS DALGLIESH, buyer, of Higher Cliffe, Strines, near Stockport, in the county of Derby, and FREDERIo HARDMAN, engineer, of 430 Chorley, Old Road, Smithills, Bolton, in the county of Lancaster, England, subjects of the King of Great Britain, have invented new and useful Improvements in the Bearings of Spindles for Spinning and Doubling Textile Fibers, of which the following is a specification.

Our invention relates to improvements in the bearings of spindles for spinning and doubling textile fibers; and the object of our improvements is to make an improved bearing for the spindle and to prevent the inner tube revolving with the spindle and from being withdrawn with the spindle.

In our improved bearing for the spindle we employ the well-known vertically-split balloon-spring, and the chief feature of novelty consists in placing this s ring, which surrounds the inner bush an footstep bearing, in the bolster below the upper bearing portion of the tube in the bolster, and thereby obtaining a more perfect bearing for the spindlethat is to say, one that adjusts itself better to any movement of the spindle. To prevent the inner tube revolving with the spindle, we secure a short pin in the inner tube and another pin secured on the bolster.

In the accompanying sheet of drawings, Figure 1 is an elevation, and Fig. 2 a sectional elevation, of a spindle fitted with our improved bearing; and Fig. 3 is a sectional plantaken on the line A B, Fig. 2.

In the drawings, a designates the bolster, the lower portion of which passes through a hole in the spindle-rail, (not shown,) said rail being gripped between the flan e a and the nut b, which screws upon the b0 ster. Inside the bolster is fitted an inner tube or liner 0, which carries the footstep and lower bearing for the spindle d. The inner tube 0 is provided with a rounded enlargement e, which fits into a corresponding recess in the bolster a, below which we, according to our invention, fit a vertically-split balloon-spring f upon the inner tube and between it and the interior of the bolster instead of placing the balloon-spring within the spindle-whirl Z and between it and the inner tube, as now customary. The rounded-off enlargement at e on the inner tube 0 and the corresponding recess in the bolster a, form practically a balland-socket joint below which the verticallysplit balloonspring f forms a bearing to counteract the pull of the spindle-band, and we find that this arrangement gives very good results and great steadiness in running.

In order to prevent the inner tube from revolving with the spindle, we form an annular recess 2 in the bolster a and we secure a short pin g to the inner tube, and another pin it is secured in the bolster, both pins projecting into said recess and both lying in the same horizontal plane when the bearing is complete, and in order to insert the inner tube into the bolster we cut away a piece of metal out of the upper part of the bolster, forming an opening at t leading to the recess 2 to allow the pin g to pass. (See Fig. 3.) By this means the inner tube cannot be withdrawn when doffing unless the pin 9 is immediately below the opening 'i. The tube 0 will rotate with the spindle until the pin g strikes the pin 7, when said rotation will cease. A passage 9' for oil is made in the upper part of the bolster (see Fig. 2) to allow oil from the oil-cup k to circulate back from the top of the bolster.

What we claim, and desire to secure by Letters Patent of the United States, is

In combination, the inner tube having a rounded enlargement formed thereon, the spindle-bolster formed with a recess to receive such enlargement, means for preventing rotation and withdrawal of the inner tube and a vertically-split balloon-spring placed between the inner tube and bolster, below such enlargement, substantially as herein set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
